Vedclass · Answer

(C) According to Lenz's law,the induced current will oppose the change in magnetic flux.The magnetic field is directed into the plane of the paper and its magnitude is increasing with time,so the magnetic flux through the loop is increasing into the plane.To oppose this increase,the induced magnetic field must be directed out of the plane of the paper.Using the right-hand thumb rule,an induced magnetic field directed out of the plane corresponds to an anticlockwise induced current in the loop.Following the anticlockwise path in the loop,the current flows from $b$ to $a$ in segment $ab$ and from $c$ to $d$ in segment $cd$ (or $d$ to $c$ depending on the specific loop geometry shown). Looking at the provided options and the loop structure,the current flows in an anticlockwise direction. Thus,in segment $ab$,the current is from $b$ to $a$,and in segment $cd$,the current is from $c$ to $d$. Since the question asks for the direction,and based on the standard interpretation of such problems,the correct choice is that the current flows anticlockwise.
